Surface volume ratio 燃烧室面容比 ; 表面体积比
The bigger the animal is, the lower its surface-to-volume ratio; for every ounce of body mass, there is proportionately less surface through which heat can escape.
动物体型越大,其体表体积比越低;躯体每增加一盎司的重量,所能散发热量的表面就成比例减少。
And if you have rough candy with a high ratio of surface area to volume, then there's more places for the bubbles to go.
如果你粗燥的硬糖具有很大的表面积,那么泡泡们就有更多的地方可以去了。
So if we want to talk about the volume of that, we just talk about the surface area, which is 4 pi r squared, and we multiply that by the thickness d r.
如果我们要讨论它的体积,我们要用的是表面面积,也就是4πr的平方,乘以厚度dr
